BACKGROUND

1. Technical Field

Exemplary embodiments relate to an ultrasound apparatus for providing again setup window for setting a gain or a list of one or more presetgains, and an information providing method which is implementable byusing the ultrasound apparatus.

2. Description of the Related Art

An ultrasound diagnosis apparatus obtains an image of soft tissues orblood flow by transmitting an ultrasound signal from a body surface ofan object toward a predetermined site inside the body, and receiving anultrasound signal reflected from tissues in the body.

The ultrasound diagnosis apparatus is small, is inexpensive, and allowsreal time display. Further, because it does not cause an exposure toradiation and thus is safe, the ultrasound diagnosis apparatus isbroadly used together with other imaging diagnosis apparatuses, such asan X-ray diagnostic apparatus, a computerized tomography (CT) scanner, amagnetic resonance image (MRI) apparatus, and a nuclear medicinediagnostic apparatus.

In general, an ultrasonic beam that propagates through tissues isreduced in amplitude or intensity as a function of a transmissiondistance. Attenuation occurs in a form that the amplitude reducesgreatly if the transmission distance is large. Due to the attenuation,the intensity of a received echo ultrasound signal may not be uniform.In particular, an ultrasound image which is based on the echo ultrasoundsignal may not have a uniform brightness or may partially have a poorquality. Accordingly, a system for allowing a user to easily compensatethe sensitivity of an ultrasound image is required.

A method for providing an ultrasound image and/or a gain setup windowfor setting a gain which is implementable by using the ultrasoundapparatus 100 will now be described in detail with reference to FIG. 2.

FIG. 2 is a flowchart which illustrates an information providing methodwhich is executable by using an ultrasound apparatus, according to anexemplary embodiment.

Referring to FIG. 2, the information providing method includesoperations which are performable by using the ultrasound apparatus 100illustrated in FIGS. 1A, 1B, and 1C. Accordingly, although notrepeatedly provided, the descriptions provided above in relation to theultrasound apparatus 100 may also be applied to the informationproviding method of FIG. 2.

In operation S210, the ultrasound apparatus 100 may obtain ultrasoundimage data which relates to an object. For example, the ultrasoundapparatus 100 may transmit ultrasonic waves to the object and maygenerate the ultrasound image data based on an ultrasound echo signalwhich is received from the object.

In operation S220, the ultrasound apparatus 100 may display, on a firstarea of a screen, a gain setup window for setting a gain with respect tothe ultrasound image data. The gain may include at least one of a timegain compensation (TGC) value and a lateral gain compensation (LGC)value.

The TGC value is a value which may be used to compensate for a reductionin intensity of an ultrasound signal based on a depth in a human body.The LGC value is a value which may be used to compensate for unevenrespective differences in attenuation due to different correspondingtransmission paths of ultrasonic beams. Hereinafter, for convenience ofexplanation, the TGC value is described as an example of the gain.

The ultrasound apparatus 100 may display, on the gain setup window, atleast one slide bar for setting the gain. For example, the ultrasoundapparatus 100 may align and display a plurality of slide bars on thegain setup window along a depth direction of an ultrasound image. Thedepth direction may refer to a direction in which a depth increases fromthe surface of an object to be diagnosed by using the ultrasoundapparatus 100 with respect to interior soft tissues.

The slide bar refers to a GUI which is configured for enabling a user toadjust the gain at a certain depth.

The slide bars may be aligned in parallel at equal intervals along thedepth direction.

When the ultrasound image data is obtained, if a gain which is set bythe user does not exist, the ultrasound apparatus 100 may display, onthe first area, an initial gain of the object based on the depth. Inthis case, the ultrasound apparatus 100 may display, on the screen, anultrasound image which is generated by applying the initial gain.

In operation S230, the ultrasound apparatus 100 may receive the gainwhich is set by the user on the gain setup window. In particular, theultrasound apparatus 100 may use the gain which is set by the user onthe gain setup window.

The ultrasound apparatus 100 may sense a touch input of the user on theslide bar. The touch input may be any one or more of a drag input and/ora tap input. For example, the user may drag an adjustment button and/ortap a certain position on the slide bar.

“Drag” refers to an operation by which the user touches the screen byusing a finger or a touch tool and then moves the finger or the touchtool to another position on the screen while continuously maintainingcontact with the screen. “Tap” refers to an operation by which the usertouches the screen by using a finger or a touch tool (e.g., anelectronic pen or a stylus) and then lifts the finger or the touch toolfrom the screen without moving it with respect to the screen.

The ultrasound apparatus 100 may extract a gain which corresponds to asensed position of the touch input. In particular, the ultrasoundapparatus 100 may obtain the gain which is set by the user with respectto a depth represented by the slide bar.

According to another exemplary embodiment, the ultrasound apparatus 100may sense a drag input of the user who performs the drag operation inthe depth direction on the gain setup window (i.e., a direction which isperpendicular to the slide bars). The ultrasound apparatus 100 mayextract individual gains which respectively correspond to depths of theultrasound image based on positions of the drag input (e.g., coordinatesof pixels where the drag input is sensed).

For example, if the user performs a drag operation on the gain setupwindow in a direction which is perpendicular to the slide bars along astraight line or a curved line, the ultrasound apparatus 100 may extractindividual gains which respectively correspond to dragged positions andmay set the gains with regard to the depths.

Based on the gains which are extracted based on the positions of thedrag input, the ultrasound apparatus 100 may move and display adjustmentbuttons on the slide bars.

In operation S240, the ultrasound apparatus 100 may display, on a secondarea of the screen, an ultrasound image to which the gain set by theuser on the gain setup window is applicable. For example, the ultrasoundapparatus 100 may newly generate or partially change the ultrasoundimage of the object by applying the gain which is set by the user to theultrasound image data.

Accordingly, the user may adjust the gain on the gain setup window whileviewing the ultrasound image to which the adjusted gain is applied inreal time. If the user sets a high gain, the ultrasound image may becomebrighter. If the user sets a low gain, the ultrasound image may becomedarker.

A method for receiving a set TGC value which is executable by using theultrasound apparatus 100 will now be described in detail with referenceto FIGS. 3, 4, 5, 6, and 7.

FIG. 3 is an image of a TGC setup screen 310 of the ultrasound apparatus100, according to an exemplary embodiment.

As illustrated in FIG. 3, the ultrasound apparatus 100 may provide, on atouchscreen, the TGC setup button 310 which is used to be provided as aknob button. Accordingly, if a user touches the TGC setup button 310 onthe touchscreen, the ultrasound apparatus 100 enters a TGC setup modefor enabling the user to set a TGC value.

FIG. 4 is an image of a gain setup window 410 for setting a gain,according to an exemplary embodiment.

As illustrated in FIG. 4, the ultrasound apparatus 100 may display, on afirst area of a screen, the gain setup window 410 for setting a gain ofultrasound image data. In this case, the gain setup window 410 mayinclude a plurality of slide bars for individually setting gainsregarding a plurality of depths. The slide bars may be aligned inparallel in a depth direction.

The ultrasound apparatus 100 may display an ultrasound image 420 of anobject on a second area of the screen. The ultrasound apparatus 100 maylocate the second area where the ultrasound image 420 is displayed inrelatively close proximity to the first area where the gain setup window410 is displayed, and thus may prevent distributed attention when theuser sets the TGC value.

Further, the ultrasound apparatus 100 may obtain a gain line 430 whichcorresponds to the gains which are set on the gain setup window 410, andmay display the gain line 430 on the second area. A detailed descriptionthereof will be provided below with reference to FIG. 6.

FIGS. 5A, 5B, and 5C are images which illustrate a screen for receivinga gain from a user, according to exemplary embodiments.

A user may set a TGC value by touching at least one slide bar and movingan adjustment button on the slide bar, or by performing a drag operationin a direction which is perpendicular to a plurality of slide bars.

As illustrated in FIG. 5A, a user may drag an adjustment button on aslide bar in a leftward direction or a rightward direction. In thiscase, the ultrasound apparatus 100 may sense the drag input of the userand may display the adjustment button at a position where the drag ends.

If the user drags an adjustment button on a first slide bar 510 in aleftward direction, a TGC value which corresponds to a depth which isrepresented by the first slide bar 510 may be reduced. In this case, aportion of an ultrasound image which corresponds to the depthrepresented by the first slide bar 510 may be reduced in brightness andthus may be displayed relatively dark.

A user may individually adjust respective TGC values which correspond toa plurality of depths by moving adjustment buttons on a plurality ofslide bars which are allocated based on the depths.

As illustrated in FIGS. 5B and 5C, a user may simultaneously set TGCvalues which individually correspond to a plurality of depths byperforming a drag operation on a gain setup window in the form of astraight line or a curved line. In this case, the ultrasound apparatus100 may sense the drag input of the user and may move and displayadjustment buttons on a plurality of slide bars to and on positionswhere the drag input is sensed.

FIG. 6 is an image which illustrates a gain line 630 which correspondsto gains, according to an exemplary embodiment.

The ultrasound apparatus 100 may obtain the gain line 630 whichcorresponds to gains which are set on a gain setup window 610, and maydisplay the gain line 630 together with an ultrasound image 620.

For example, the ultrasound apparatus 100 may obtain the gain line 630by connecting positions of adjustment buttons 611 on a plurality ofslide bars (i.e., gains represented by the adjustment buttons 611). Inthis case, the ultrasound apparatus 100 may interpolate and calculate again between a first slide bar and a second slide bar by using a gain onthe first slide bar and a gain on the second slide bar.

Further, if a user sets the gains by performing a drag operation on thegain setup window 610 in the form of a straight line or a curved line,the ultrasound apparatus 100 may obtain the gain line 630 based oncorresponding dragged positions.

The ultrasound apparatus 100 may display the gain line 630 whichcorresponds to the gains which are set by the user on the gain setupwindow 610, adjacent to the ultrasound image 620 based on positions ofdepths of the ultrasound image 420, and thus may enable the user tointuitionally check, for example, a shape and/or a slope of the gainline 630.

Although FIG. 6 shows an example in which the gain line 630 is displayedon a right side of the ultrasound image 620, the gain line 630 is notlimited thereto. In particular, the gain line 630 may be displayed on abottom side, a top side, or a left side of the ultrasound image 620.

FIG. 7 is an image which illustrates a list 710 of preset gains,according to an exemplary embodiment.

As illustrated in FIG. 7, the ultrasound apparatus 100 may display thelist 710 of one or more preset gains on a third area of a screen. Thepreset gain(s) may be previously set by a user or a system.

The list 710 of the preset gains may be displayed as images of gainlines which respectively correspond to the preset gains. In this case,the gain line may be variously displayed, for example, in the form ofany one or more of a solid line, a dotted line, a dashed line, and/or adotted and dashed line. The preset gain may be displayed in the form ofan image which includes a plurality of slide bars.

The preset gains which are included in the list 710 may be automaticallyset by the ultrasound apparatus 100 or may be manually set by the user.

For example, the ultrasound apparatus 100 may extract and displaytypically and frequently used preset gains on the list 710, or maydisplay preset gains selected by the user on the list 710.

The ultrasound apparatus 100 may extract a preset gain to be displayedon the third area of the screen based on at least one of probe setupinformation, application information, and object information. Forexample, if the user selects a 1D linear probe, the ultrasound apparatus100 may extract a preset gain which is stored and mapped to the 1Dlinear probe and may display the extracted preset gain on the list 710.Further, if the user selects obstetrics (OB) from among a plurality ofapplications, the ultrasound apparatus 100 may extract a preset gainwhich relates to the application selected by the user and may displaythe extracted preset gain on the list 710.

The ultrasound apparatus 100 may further display at least one of a bodymarker, the application information, and the probe setup information onthe list 710.

The application information refers to information which relates to adiagnosis department and/or a diagnosis site for ultrasound diagnosis.The diagnosis department may include any one or more of obstetrics (OB),gynecology (GYN), pediatrics (PD), chest surgery (CS), radiology (RD),neurosurgery (NS), abdomen, etc.

The body marker refers to a figure which represents a position or anobject into which ultrasonic waves are scannable. Examples of the bodymarker may include any one or more of a liver shape, a heart shape, anda uterus shape. The probe setup information may refer to informationwhich is set in relation to a probe which is configured for outputtingan ultrasound signal. For example, when a low-frequency curved probe isused, ‘low frequency convex’ may be further displayed in addition to acorresponding preset gain. If a high-frequency linear probe is used,‘high frequency linear’ may be further displayed in addition to acorresponding preset gain.

The ultrasound apparatus 100 may receive a selection of one preset gainon the list 710. The ultrasound apparatus 100 may display the selectedpreset gain on a gain setup window, and may display, on a second area ofa screen, an ultrasound image to which the selected preset gain isapplied. In this case, the ultrasound apparatus 100 may receive anadditional setup from the user in relation to the selected preset gain.In particular, the user may adjust the gain which is displayed on thegain setup window in detail by entirely or partially adjusting thedisplayed gain.

The ultrasound apparatus 100 enables the user to easily set a TGC valueby providing a few types of preset TGC values.

The ultrasound apparatus 100 may provide an initialization button 720for initializing the gain which is set on the gain setup window. If atouch input on the initialization button 720 is sensed, the ultrasoundapparatus 100 may display an initial gain on the gain setup window andmay display, on the second area of the screen, an ultrasound image towhich the initial gain is applied.

FIG. 8 is a flowchart which illustrates a gain storing method which isexecutable by using the ultrasound apparatus 100, according to anexemplary embodiment.

In operation S810, the ultrasound apparatus 100 may receive, from auser, a request to store a gain which is set on a gain setup window. Theuser may transmit such a request by touching a certain icon which isdisplayed on a screen or by selecting a physical button.

In operation S820, the ultrasound apparatus 100 may store, in the memory160, the gain which is set on the gain setup window. The ultrasoundapparatus 100 may store the gain which is set on the gain setup windowby mapping the gain to at least one of probe setup information andapplication information. In addition, the ultrasound apparatus 100 maystore the gain which is set on the gain setup window by connecting thegain to at least one parameter which has previously been set in relationto an ultrasound image. A detailed description thereof will be providedbelow.

In operation S830, the ultrasound apparatus 100 may display an image ofthe stored gain in a third area. For example, if the user selects a savebutton, the ultrasound apparatus 100 may store, in the memory 160, again which is currently displayed on the gain setup window, and maydisplay the gain which is currently displayed on the gain setup windowon a list of preset gains. A detailed description thereof will beprovided below with reference to FIG. 9.

FIGS. 9A, 9B, and 9C are images which illustrate a GUI which isconfigured for storing a gain, according to an exemplary embodiment.

As illustrated in FIG. 9A, the ultrasound apparatus 100 may output asave button 930 on a touchscreen. In this case, the ultrasound apparatus100 may sense a touch input of a user on the save button 930. In thiscase, the ultrasound apparatus 100 enters a save mode.

As illustrated in FIG. 9B, when operating in the save mode, theultrasound apparatus 100 may identifiably display an area (or a slot)for displaying a gain which is currently displayed on a gain setupwindow 910 on a list 940 of preset gains. For example, the ultrasoundapparatus 100 may display a yellow frame around buttons 941, 942, and943 for displaying images of the preset gains.

If a selection of the third button 943 is received from the user, asillustrated in FIG. 9C, the ultrasound apparatus 100 may store, in thememory 160, the gain which is currently displayed on the gain setupwindow 910, and may display, on the third button 943, an image of thegain which is currently displayed on the gain setup window 910.

Although FIG. 9C shows an example in which the image of the third button943 is changed, according to an exemplary embodiment, the ultrasoundapparatus 100 may newly generate a button for displaying the gain whichis currently displayed on the gain setup window 910 and may furtherdisplay the newly generated button next to the third button 943.

Accordingly, because the ultrasound apparatus 100 may display, on acertain button, a gain curve which corresponds to a current TGC value,the user may intuitionally check the stored TGC value (or a TGC line).

The ultrasound apparatus 100 may provide, on the touch screen, a closebutton 950 for closing a TGC setup mode. If a touch input of the user onthe close button 950 is sensed, the ultrasound apparatus 100 may closethe TGC setup mode.

According to another exemplary embodiment, if a touch input of the useris not sensed for a predetermined period of time, the ultrasoundapparatus 100 may automatically close the TGC setup mode.

FIG. 10 is an image which illustrates a gain setup window for setting anLGC value, according to an exemplary embodiment.

Although a TGC value is described above as an example of a gain, thedescriptions of the TGC value with respect to FIGS. 3 through 9 may alsobe applied to the LGC value.

As illustrated in FIG. 10, the ultrasound apparatus 100 may provide anLGC setup window on a touchscreen. For example, the ultrasound apparatus100 may align a plurality of slide bars for setting LGC values inparallel in the LGC setup window.

In this case, a user may individually set each respective one of the LGCvalues by adjusting each of the slide bars, or may simultaneously setthe LGC values by performing a drag operation in a direction which isperpendicular to the slide bars (a lateral direction) in the form of astraight line or a curved line.

The ultrasound apparatus 100 may display, on a screen in real time, anultrasound image to which the LGC values set by the user are applied. Inaddition, the ultrasound apparatus 100 may store, in the memory 160, theLGC values which are set by the user, and may display a list of presetLGC values on the screen. A detailed description thereof is similar tothe above description of the TGC value and thus is not provided here.Although the TGC setup window and the LGC setup window are displayedseparately, the ultrasound apparatus 100 may also display the TGC setupwindow and the LGC setup window on the same screen.

The ultrasound apparatus 100 may extract one or more preset gains fromthe memory 160 or from a personalized server (e.g., a cloud server) andmay form a list of the extracted preset gains. In particular, theultrasound apparatus 100 may obtain a list of preset gains from any oneor more of an external storage medium and/or an internal storage medium.

According to another exemplary embodiment, the ultrasound apparatus 100may receive a list of preset gains from an external apparatus via wiredand/or wireless communications.

In operation S1120, the ultrasound apparatus 100 may receive a selectionof one preset gain which is included in the list. For example, theultrasound apparatus 100 may sense a touch input (e.g., a tap gesture, aswipe gesture, or a flick gesture) or a voice command of a user inrelation to one preset gain.

In operation S1130, the ultrasound apparatus 100 may apply the selectedpreset gain to ultrasound image data of an object. The ultrasoundapparatus 100 may display, on the screen, an ultrasound image to whichthe selected preset gain is applied.

The ultrasound apparatus 100 may display, on a gain setup window, thepreset gain which is selected by the user. For example, the ultrasoundapparatus 100 may move at least one slide bar which is displayed on thegain setup window, based on the selected preset gain.

The ultrasound apparatus 100 may receive an additional setup from theuser in relation to the preset gain which is displayed on the gain setupwindow. For example, the user may adjust the preset gain which isdisplayed on the gain setup window in detail by adjusting the slide barwhich is displayed on the gain setup window.

The ultrasound apparatus 100 may store the gain which is additionallyset by the user. In this case, the ultrasound apparatus 100 may storethe gain which is additionally set by the user in at least one of aninternal storage medium and/or an external storage medium (e.g., auniversal serial bus (USB) memory or an optical disk).

In this case, the ultrasound apparatus 100 may further display, on thelist of the preset gains, the gain which is stored in the internalstorage medium and/or the external storage medium.

The ultrasound apparatus 100 may transmit the preset gain and/or thelist of the preset gains to an external apparatus via wired and/orwireless communications. The external apparatus may be, but is notlimited to, any one or more of a device of the user (e.g., a mobilephone, a smart phone, a laptop computer, a tablet PC, or an electricbook device), another ultrasound apparatus, and/or a personalized server(e.g., a cloud server).

In operation S1230, the ultrasound apparatus 100 may display anultrasound image of the object on a second area of the screen based onthe obtained ultrasound image data.

In operation S1240, the ultrasound apparatus 100 may display a list ofpreset gains on a third area of the screen. The ultrasound apparatus 100may obtain the list of the preset gains from an external storage medium.

The ultrasound apparatus 100 may receive a selection of one preset gainfrom among the preset gains included in the list. The ultrasoundapparatus 100 may display the selected preset gain on the gain setupwindow, and may display, on the second area of the screen, an ultrasoundimage to which the selected preset gain is applied.

For example, as illustrated in FIG. 9A, the ultrasound apparatus 100 maydisplay the gain setup window 910, an ultrasound image 920, and the list940 of the preset gains on one screen. In this case, a user may set aTGC value and/or an LGC value by directly adjusting slide bars which aredisplayed on the gain setup window 910, or may select one preset gain(e.g., item 943 of FIG. 9B) from among the preset gains which aredisplayed on the list 940.

If the user selects one preset gain (e.g., item 943) from among thepreset gains which are displayed on the list 940, the ultrasoundapparatus 100 may display the selected preset gain (e.g., item 943) onthe gain setup window 910. The ultrasound apparatus 100 may receive anadditional setup from the user in relation to the preset gain which isdisplayed on the gain setup window 910. The ultrasound apparatus 100 maystore, in the memory 160 and/or in an external storage medium, the gainwhich is additionally set on the gain setup window 910, and may displayan image of the stored gain on the list 940 of the preset gains.

The ultrasound apparatus 100 may display at least one parameter which ismapped to the selected preset gain (e.g., item 943). According toanother exemplary embodiment, the ultrasound apparatus 100 may determineat least one parameter which is mapped to the selected preset gain(e.g., item 943) and may apply the determined parameter to a system. Inparticular, the ultrasound apparatus 100 may change the setup of anultrasound system based on at least one parameter which is mapped to theselected preset gain (e.g., item 943). A detailed description thereofwill be provided below with reference to FIGS. 13, 14, 15, 16, and 17.

FIGS. 14A and 14B are images which illustrate a GUI which is configuredfor setting parameters which relate to an ultrasound image, according toan exemplary embodiment.

The ultrasound apparatus 100 may provide a setup window 1400 which isconfigured for enabling a user to individually set the parameters whichrelate to the ultrasound image.

For example, as illustrated in FIG. 14A, the ultrasound apparatus 100may provide, on a screen, the setup window 1400 for setting parameterssuch as the frequency 1305, the dynamic range 1310, the frame average1315, the reject level 1320, the gray map 1325, the DMR+ 1335, theharmonic 1340, the speed 1355, and the FSI 1370.

The ultrasound apparatus 100 may sense a parameter which is input (orselected) by a user on the setup window 1400. The ultrasound apparatus100 may store the input (or selected) parameter in response to a requestof the user to store the parameter. A detailed description thereof willbe provided below with reference to FIG. 15.

FIGS. 15A, 15B, 15C, and 15D are images which illustrate a GUI which isconfigured for enabling a user to store at least one preset parameter,according to an exemplary embodiment.

As illustrated in FIG. 15A and FIG. 15B, if a user touches a certainicon on the touchscreen 131 or selects a certain button on the controlpanel 132, the ultrasound apparatus 100 may provide a GUI 1500 forstoring a parameter which is set by the user.

For example, if a selection of a probe button 1510 by the user issensed, the ultrasound apparatus 100 may provide, on the touchscreen131, the GUI 1500 for adjusting a gain or at least one parameter whichrelates to an ultrasound image.

As illustrated in FIG. 15B, the ultrasound apparatus 100 may display, ona predetermined area of the GUI 1500, a probe list 1520 which includesidentification information which relates to one or more probes which areconnected to the ultrasound apparatus 100. For example, if a probe 1C2-8, a probe 2 L5-13, and a probe 3 VE 4-8 are connected to theultrasound apparatus 100, the ultrasound apparatus 100 may displayidentification information which relates to each of the probe 1 C2-8,the probe 2 L5-13, and the probe 3 VE4-8 on the probe list 1520.Identification information which relates to a probe is information whichmay be used for identifying the probe and may include, for example, anyone or more of a probe image, a probe name, and a probe type.

The ultrasound apparatus 100 may sense a selection of at least one probefrom the probe list 1520 by the user. For example, the user may selectthe probe 3 VE4-8 from the probe list 1520.

In addition, the ultrasound apparatus 100 may display a list 1530 ofapplications (e.g., diagnosis departments) on the predetermined area ofthe GUI 1500 and may receive a selection of an application from the list1530 by the user. For example, the user may select “Abdomen” from thelist 1530 of the applications.

In this case, the ultrasound apparatus 100 may display a list of presetswhich correspond to the probe 3 VE 4-8 which is selected by the user.Further, according to another exemplary embodiment, the ultrasoundapparatus 100 may display a list of presets which correspond to theprobe 3 VE 4-8 and the application (e.g., “Abdomen”) which are selectedby the user. In this case, the list of the presets may include systempresets which include parameters which are previously set by a systemand are unchangeable, and user presets which include parameters whichare arbitrarily set by the user.

The ultrasound apparatus 100 may provide, on the GUI 1500, a defaultarea 1540 for displaying the system presets which are mapped to theparameters which are previously set by the system and are unchangeable,and an arbitrary area 1550 for displaying the user presets which aremapped to the parameters which are arbitrarily set by the user.

If the user selects one preset item (e.g., “fetal heart”) from the listof the presets which respectively correspond to at least one of theprobe and the application and then touches a predetermined button 1560,the ultrasound apparatus 100 may provide preset parameters whichcorrespond to the selected preset item (i.e., “fetal heart”).

For example, as illustrated in FIG. 15C, the ultrasound apparatus 100may display preset parameters which respectively correspond to each ofthe frequency 1305, the frame average 1315, the gray map 1325, theharmonic 1340, the line density 1365, and the focus number 1375 whichare mapped to the selected preset item (i.e., “fetal heart”). In thiscase, the user may generate a new user preset by changing the parameterswhich are displayed on a screen. The newly generated user preset may bedisplayed on the arbitrary area 1550. In this case, the user may set aname of the newly generated user preset.

For example, a first user may generate a user preset named ‘user 1’ andmay store a plurality of parameters which are set by the first user bymapping the parameters to ‘user 1’. In addition, a second user may storea plurality of parameters which are set by the second user by mappingthese parameters to a user preset named ‘user 2’. If a third user setsparameters in relation to a face of a fetus (i.e., a different selectedpreset item), the third user may store the parameters which are set inrelation to the face of the fetus by mapping these parameters to a userpreset named ‘Face’.

Further, the user may set a gain and may generate a new user preset byadding the set gain. For example, if the user touches a TGC button onthe screen, the ultrasound apparatus 100 may provide a setup window forsetting the gain (e.g., a TGC value).

As illustrated in FIG. 15D, the ultrasound apparatus 100 may provide again setup window and may receive a gain which is set by the user on thegain setup window. A method thereof is described in detail above andthus is not described here.

If the ultrasound apparatus 100 receives, from the user, a request tostore the set gain, the ultrasound apparatus 100 may generate a userpreset which includes the set gain. In this case, the gain which is setby the user may be mapped to at least one of a probe (e.g., the probe 3)and application information (e.g., Abdomen) which are selected by theuser and may be stored as a user preset. The gain which is set by theuser may be stored as a user preset in the arbitrary area 1560 togetherwith preset parameters. Accordingly, the ultrasound apparatus 100enables the user to make a frequently-used TGC line for each probe andto store the TGC line as a user preset. For example, the user may storea TGC line which is frequently used for a carotid ultrasound image bymapping this TGC line to a probe which is used for generating thecarotid ultrasound image. In this case, the ultrasound apparatus 100 maygenerate a preset mapping table which includes the identificationinformation which relates to the probes, the parameters which relate tothe ultrasound image, and the gains, which are mapped to each other, andmay store the preset mapping table in the memory 160.

Although FIGS. 15A, 15B, 15C, and 15D show an example when a probe andan application are selected first and then a parameter is adjusted or aTGC value is set, according to an exemplary embodiment, the parameter orthe TGC value may be set first and then the probe or the application maybe selected and connected to the set parameter or the TGC value.

A method for automatically extracting a gain which is stored and mappedto a probe and applying the gain to a system by the ultrasound apparatus100 will now be described.

FIG. 16 is a flowchart which illustrates an information providing methodwhich is executable by using the ultrasound apparatus 100 based onidentification information of a probe, according to an exemplaryembodiment.

In operation S1610, the ultrasound apparatus 100 may determineidentification information which relates to a probe which is connectedto the ultrasound apparatus 100. For example, the ultrasound apparatus100 may determine identification information which relates to a probewhich is connected to the ultrasound apparatus 100, for example, a probeimage, a probe name, and a probe type, by receiving the identificationinformation which relates to the connected probe which is stored in thememory 160.

If a plurality of probes are connected to the ultrasound apparatus 100,the ultrasound apparatus 100 may determine identification informationwhich relates to each of the probes and may display a probe list whichincludes the identification information which relates to each of theprobes.

In operation S1620, the ultrasound apparatus 100 may extract a presetgain which corresponds to the identification information which relatesto the probe.
